Log Messages • The switch maintains in-memory log messages as well as persistent logs. You can also conﬁgure remote

logging so that the switch sends log messages to a remote log server. You can also conﬁgure the switch

to send log messages to a conﬁgured SMTP server. This allows you to receive the log message in an

e-mail account of your choice. Switch auditing messages, CLI command logging, and SNMP logging can be

enabled or disabled.

System Time Management • The switch will obtain the system time and date through NTP (Network Time Protocol) service of Linux

server, or you can set the time and date locally or conﬁgure the time zone on the switch via Linux.

Source IP Address Conﬁguration • Syslog, TACACS, SNTP, sFlow, SNMP Trap, RADIUS, and DNS Clients allow the IP Stack to select the source

IP address while generating the packet. This feature provides an option for the user to select an interface

for the source IP address while the management protocol transmits packets to management stations. The

source address is speciﬁed for each protocol.

Multiple Linux Routing Tables • On Linux systems, local and default IPv4 routes for the service port and network port are installed in

routing tables dedicated to each management interface. Locally-originated IPv4 packets use these routing

tables when the source IP address of the packet matches an address on one of these interfaces. This

feature allows the Linux IP stack to use default routes for dierent interfaces simultaneously.

Open Network Install Environment Support • Open Network Install Environment (ONIE) allows customers to install their choice of network operating

system (NoS) onto a switch. When the switch boots, ONIE enables the switch to fetch a NoS stored on a

remote server. The remote server can hold multiple NoS images, and you can specify which NoS to load

and run on the switch. ONIE support in the switch soware facilitates automated data center provisioning

by enabling a bare-metal network switch ecosystem.

• ONIE is a small operating system. It is preinstalled as ﬁrmware and requires an ONIE-compliant boot

loader (U-Boot/BusyBox), a kernel (Linux) and the ONIE discovery and execution application. For more

information about ONIE, see http://onie.github.io/onie.

Interface Error Disable and Auto Recovery • If the switch detects an error condition for an interface, it places the interface in the diagnostic disabled

state by shutting down the interface. The error-disabled interface does not allow any trac until it

is reenabled. You can manually reenable the interface, or, if the Auto Recovery feature is enabled, the

interface can be reenabled automatically aer a conﬁgurable time-out period.

• There are multiple reasons that may cause the switch to place an interface in the error-disabled state.

Auto Recovery can be conﬁgured to take eect if an interface is error-disabled for any reason, or for some

reasons but not others.

CLI Scheduler • The CLI scheduler allows administrators to schedule fully-qualiﬁed EXEC mode CLI commands to run once,

at speciﬁed intervals, at speciﬁed calendar dates and times, or upon system startup. CLI scheduler has

two basic processes. A policy list is conﬁgured containing lines of fully-qualiﬁed EXEC CLI commands to be

run at the same time or same interval. One or more policy lists are then scheduled to run aer a speciﬁed

interval of time, at a speciﬁed calendar date and time, or upon system startup. Each scheduled occurrence

can be set to run either once only or on a recurring basis.

Routing Features

IP Unnumbered • Each routing interface can be conﬁgured to borrow the IP address from the loopback interfaces and use

this IP for all routing activities. The IP Unnumbered feature was initially developed to avoid wasting an

entire subnet on point-to-point serial links. The IP Unnumbered feature can also be used in situations

where adjacencies are transient and adjacent interfaces cannot be easily conﬁgured with IPv4 addresses

in the same subnet. It also helps in reducing the conﬁguration overhead in large scale Data-Center

deployments.

Open Shortest Path First (OSPF) • Open Shortest Path First (OSPF) is a dynamic routing protocol commonly used within medium-to-large

enterprise networks. OSPF is an interior gateway protocol (IGP) that operates within a single autonomous

system.
